Alright guys, I need some help. A little info on my setup- I purchased the G90 second hand on ebay (perhaps the first mistake, I was waiting on getting the funds for an Evo 1.00 but oh well) so I have no history of the engines use or care of the engine. I am using a new SuperTigre Sport Glow Plug Medium Heat Range from towerhobbies.com. The prop on the engine as seen in the below video is a Master Airscrew 14x8. I have also tried and MAS 13x8 and APC 12x6 and all end in the same result. I think that I am not getting a rich mixture at all and the engine overheats and shuts off when I move past 1/2 throttle. It will idle for 5 to 8 minutes and shut off. I am not sure what I need to do. I am hoping that the video will shed some insight from you experts. Also, I am using Cool Power Max 15% as fuel.
